As our customers build even more powerful applications in Azure by using Azure SQL Database, they need more options to scale performance for high-demand workloads. That’s why we’re announcing a new performance level within our Premium service tier: P15. P15 offers 4000 Database Transaction Units (DTUs)—that’s twice as powerful as our P11 offering—with extremely fast transactional performance, real-time analytics, and up to 1 TB of storage.

An advantage to running a SQL database on Azure is being able to scale performance up or down, on the fly, to adapt to changing workload demands. This new performance level lets you scale up database performance for explosive growth of application workloads.
